Introduction With the development of missile weapons, new material and manufacture technology continue to merge, and a number of breakthroughs are seen in the area of isolation thermal materials.
Composite materials are considered high specific strength and modulus, highly resistant to high-temperature, ablation and impact, therefore it is being widely used in astronautics and aeronautics industries, replacing the traditional materials such as ferrous and non-ferrous metals and dominating the materials for thinner and thermal-resistance structures.

In the teaching reform including investigative study and the integration of information technology, is generally accepted that the integration of information technology with curriculum strategy are: optimizing the course structure of space and time, innovation course materials, course materials bag is mainly composed of electronic schoolbag, local curriculum material storage, remote material storage and teaching platform.
And based on the supporting materials, many schools draw lessons from foreign experience, to fixed teaching material in the form of notes, reduce practice principle part, don't write practical steps, mainly is the question for higher College of Engineering students to solve.
